This book covers diverse environmental issues such as climate change; biodiversity preservation; prevention of air, water, and soil pollution; and resource recycling. Readers can acquire these four practical interdisciplinary abilities: 1. knowledge; 2. technology; 3. evaluation; and 4. strategy in the diverse issues related to the environment. These abilities are fundamental to identifying the core essence of economic and ecological interdependence, to look at and analyze problems from an overarching perspective, and to consider countermeasures to be taken. Each chapter of this book...

The idea of the Grobner basis first appeared in a 1927 paper by F. S. Macaulay, who succeeded in creating a combinatorial characterization of the Hilbert functions of homogeneous ideals of the polynomial ring. Later, the modern definition of the Grobner basis was independently introduced by Heisuke Hironaka in 1964 and Bruno Buchberger in 1965. However, after the discovery of the notion of the Grobner basis by Hironaka and Buchberger, it was not actively pursued for 20 years. A breakthrough was made in the mid-1980s by David Bayer and Michael Stillman, who created the Macaulay computer...

This book explicates the optical controls of antiferromagnetic spins by intense terahertz (THz) electromagnetic waves. The book comprises two key components: (1) the experimental demonstration of the enhancement of a THz magnetic field using a split-ring resonator (SRR) and (2) the control of the direction of magnetization by using the enhanced THz magnetic field to break the symmetry of optically-induced phase transition. These make up the first step leading to future spintronics devices.

In the beginning of the book, the author reviews the basics of the ultrafast laser and...
